Abstract

The invention provides an improved star-shaped feeding machine which can quickly disperse materials stacked in blocks, lock the air of a boiler on the premise of meeting the use requirement of the boiler, and reduce the possibility of fire hazard. The feeding machine comprises a stander, a motor is installed on the stander which is provided with a feeding funnel; the feeding funnel is internally provided with a rotor which is connected with the motor by a chain and a chain wheel, the rotating shaft of the rotor is vertical to the center line of the funnel, a U-shaped funnel is arranged at the combination part of the rotor and the funnel, the bottom of the U-shaped funnel is open, and the outer edge of the rotating vane of the rotor is contacted with the U-shaped funnel. The feeding machine is characterized in that: the U-shaped funnel is installed on the funnel by a supporting rotating shaft, and an anti-blockage device is arranged outside the combination circular arc part of the rotor and the U-shaped funnel.

Description

(1) Technical field [0001] The invention relates to the technical field of storage equipment for materials used in biomass combustion furnaces, in particular to an improved star feeder. (2) Background technology [0002] With the decrease of energy, biomass fuel has increasingly become another source of fuel for the boiler industry. Due to the particularity of biomass fuel itself, it is bulky, takes up space, and is inconvenient to store. Now the industry has designed a star-shaped feeder, which can quickly disperse the materials accumulated in blocks to meet the requirements of the boiler. However, since the boiler is a negative pressure furnace, it is required that the feeder be able to lock the gas while feeding the material to prevent tempering. And existing feeder, its structure sees figure 1 , when feeding, the material is easy to be stuck between the rotor and the U-row bucket, so there will be a large leakage space between the rotor and the U-row bucket, and the lo...
